Big Data is emerging as an opportunity for organizations. It has made organizations realize that there are lots of benefits by Big Data Analytics. Organizations are now examining large data sets to uncover all hidden patterns, unknown correlations, market trends, customer preferences and other useful business information.
These analytical findings are helping organizations in more effective marketing, new revenue opportunities, and better customer service. They are improving operational efficiency, competitive advantages over rival organizations and other business benefits. Previously, there were many issues related to Big Data and traditional processing system. In this post, we will discuss what Hadoop is, and how Hadoop emerged as a solution to the problems associated with Big Data. We are also listing 5 reasons to learn Big Data Hadoop skills highlighting the benefits of using Hadoop.
Traditional Hadoop Approach & Problems with Big Data
If we look at the traditional Hadoop approach, there was an issue of handling the heterogeneity of data- structured, semi-structured and unstructured. The tradition method, RDBMS, was used to process big data. This focuses mostly on structured data like banking transaction, operational data etc. Whereas the new Hadoop specializes in semi-structured, unstructured data like text, videos, audios, Facebook posts, logs, etc. RDBMS technology is a proven, highly consistent, matured systems supported by many companies. While on the other hand, Hadoop is in demand due to Big Data, which mostly consists of unstructured data in different formats. Here are the major problems associated with processing Big data in past time:
- The first problem is storing the colossal amount of data. Storing this huge data in a traditional system is not possible since the storage being limited only to one system and the data is being increasing at a tremendous rate.
- Second problem with the traditional Hadoop approach is storing heterogeneous data. Here the data is not only huge, but it is present in various formats as well like: Unstructured, Semi-structured and Structured. To store all these varieties of data, we needed a system generated from various sources.
- Third problem is accessing and processing speed of data. The hard disk capacity is increasing but the disk transfer speed is not increasing at similar rate. Explaining this situation with an example: Assume you have only one 100 Mbps I/O channel and you are processing 1TB of data, it will take around 2.91 hours. Now, if you have four machines with one I/O channel, for the same amount of data it will take 43 minutes approx. Thus, accessing and processing speed is the bigger problem than storing Big Data.
Hadoop New Approach- What is Hadoop?
Hadoop is a framework that allows you to store Big Data in a distributed environment, so that, you can process it parallely. Today, Hadoop can be used for:
- Search – Yahoo, Amazon, Zvents
- Data Warehouse – Facebook, AOL
- Log processing – Facebook, Yahoo
- Video and Image Analysis – New York Times, Eyealike
In total, we can conclude that:
- Hadoop is scalable and excellent for Big Data analytics
- Oracle is proven for concurrent transactional workloads
- Oracle APIs for legacy applications and OLTP workloads
- Solutions are available to integrate Oracle and Hadoop
- Scalability on commodity Hardware for analytic workloads
- There is a great value in using hybrid systems (Oracle + Hadoop)
